edge to assume the same are as the inner face of the plate I.

I further locate the fold edge I3 of the plate ear Ii on a line midway the width of :the inter mediate fastening prongs 4 so that the center line of the ear 6 between thefront-and rear faces thereof will be in a straight line with the midway points of the prongs 4, thus causing the ear 6 to, serve as a truss member on the plate directly between the opposed fastening prongs 4.

I provide the fold-edge I3 of ear 6 with a suitable relief opening I4 midway the ends thereof, which opening-serves to prevent distortion of the ear 6 when 'bending the ear downwardly relative to' the plate I, by breakingthe otherwise continuous fold line I3 to relieve crowding ofthe metaladjacent the lock pin receiving opening 8, and thereby permit the fold edge I3 to assume the same are as the inner face of the plate I. 1

.Thisarrangement of the ears 5 and 6 relative to thefastening prongs 2 and 4 serves to provide a heal fastening plate which will be proper- 1y reinforced or stiffened directly between the aforesaid fastening prongs. v

By providing the ears 5 and 6 of the plate I with the relief openings I2 and so as to extend beyond both sides of the fold edge thereof, the openings! and 8 in the ears 5 and 6 will not be disturbedas toregister thereof after the ears havebeen bent orfolded into proper position rela- 'tive to the plate body. I. [This is important so thatafter-v theheel has been forced to the heel seatlA of a shoe sole under pressure of a. plunger B,"'therewill be no difficulty in forcing a lock pinIS through the ear openings I and 8 after having been inserted into an opening Ili, in a heel C,.after theheel having slotted recesses II and I8 to receive the apertured ears of the plate has-:beenpositioned on the heel seat of the shoe sole and held in properposition by suitable pressure to cause the heel opening I6 to register with the-ear openings I and 8.

YD'ue to the pressure exerted on the heel for holding it-properly on the heel seat of the shoe, it is .apparent that after .the'pressure has been released, the resiliency of the plate and the natural tendency of the heel to move outwardly dueto the peripheral edge thereof having been forced into the flexiblematerialof the heel seat, the pinwill bind in the ear. opening;- thereby sel'curelyholdmg and locking the heel against dis.-

prong faces serves to cause the prongs to be forced straight through the heel seat material of the shoe and to clinch at will when the points of the prongs are brought into contact with a plate 2I on a last 22 upon which thershoe to be provided with'the heel fastening plate is lasted.

In a modified form of fastening prongs one of which is shown in Fig.9, the same is beveled as at I9 on the outer face on1y,.thus causing the points of the prongsv to bend lnwardlyand against the insole of the heel seat material when'brought into instant contact with the anvil plate 2I of th'e'last 22.

I WhatIclaimis: 1. Incombination witha shoe heel".a'ttachingj plate structure having-a pair of 'apert'uredlock pin, engaging ears, adapted to be permanently secured to the heel seat of a shoe sole by opposed pairsof fastening prongs, of bevel faceson; the.. rong's, the front pair of prongs having their, front edges at the juncture thereof. with the plate disposed-in lock pin engaginglears.

4 0 versely with a flat marginaledge and there is; T

2. In combination with a heel attaching plate adapted to be permanently secured to the heel seat of a shoe sole by fastening prongs, of beveled faces on the prongs, an apertured ear disposed directly between two prongs at the front corners of the plate with the front edges of said prongs at the juncture thereof with the plate being in a plane with the front face of the apertured ear so that the apertured ear will serve as a truss member for the front edge of the plate.

3. In combination with a heel attaching plate adapted to be permanently secured to the heel seat of a shoe sole by fastening prongs, of beveled faces on the prongs, an apertured ear disposed directly between two prongs at the front corners of the plate with the front edges of said prongs at the juncture thereof with the plate being in a plane with the front face of the apertured ear so that the apertured ear will serve as a truss member for the front edge of the plate, a second apertured ear disposed directly between the pair of opposed I prongs to the rear of the front pair of prongs and the juncture thereof with the plate being in a' plane with the front face of the apertured ear so that the apertured ear will serve as a truss member for the front edge of the plate, a second apertured ear disposed directly between the pair of opposed prongs to the rear of the front pair of prongs and serving as a truss member for the plate between said pair of prongs to the rear of the front pair of prongs and the fold edge of the front apertured ear having a relief opening midway its ends to prevent distortion of the ear when bending into position to prevent misalignment of the aperture of the front ears with the aperture of the ear disposed to the rear of the front ear.

5. In combination with a heel attaching plate having fastening prongs and apertured lock pin engaging ears, of beveled inner and outer'faceson the prongs and the fold edge of one of the ears having an opening midway its ends to relieve the crowding of metal in bending'the ear into final position at a right angle to the plate.

6. In combination with a heel attaching plate having fastening prongs and apertured lock pin engaging ears, of beveled inner faces on the prongs and the fold edge of one of the earshaving an opening midway its ends to relieve the crowding of metal in bending the ear into final position at a right angle to the plate.

7. In combination with a heel attaching plate having fastening prongs and apertured lock pin engaging ears, of beveled outer faces on the prongs and the folded edge of one of the ears having an opening midway its ends to relieve the crowding of metal in bending the ear into final position at directly between the intermediate pair of opposed fastening prongs.

9. A heel attaching plate having a dished body portion, apertured ears struck up from the material of said body portion and said dished body portion having its peripheral edge portion flattened relative thereto to provide unbroken upper and lower marginal plane surfaces therefor.
